Dionex ED50A Electrochemical Detector
The first waveform step at 0.00 s is the initial potential of -0.80 V. To
calculate the time for the second step, divide the total voltage scanned by
the desired sweep rate:
The time for the second step is 14 s. The third step is an equal interval
later, or 28 s.

Running the Waveform
When the cell is turned on, the Dionex ED50A applies the initial potential
programmed at time zero. At that point, you may do any of the following:
